In my previous incarnation, I sold and shipped a lot of Harbour Lights. Almost always used USPS Priority Mail and insured for the full amount. Most always bought NEW boxes -- and USED peanuts. Now I have no peanuts to fill my collection boxes should I need to move those. (Have you priced plastic peanuts? WOW)

I think $10-12 is a fair amount for shipping a $500-$800 lighthouse, but competition forced that down to $8-$10. (For one lighthouse). On multiple purchases, it was often a matter of charging actual shipping costs (no box, no peanut costs.)

The dealer from which I buy my Harbour Lights charges no shipping - but ships them parcel post uninsured, and uses 'used' boxes and shredded paper as packing. Sometimes the HL box doesn't come through perfect, but the lighthouse does.
